from my understanding the oil injectors are just a 1 way valve, w/o the pressure from oil going into it, it would open to the atmosphere under vaccum

No problems during vacuum. I'll check with Steve Kan just to be sure that they won't. My motor went( due to old age ) and he is replacing it for me. I'll ask him tommorow and get back with you.

Steve isn't a fan of premix but I most definitely am. I don't like the factory oil metering systems (any of them) due to their dependence on these four, goofy nylon tubes known as oil injection lines. They seem to be quite fragile (especially the old factory ones) and tend to break when tugged on.



I personally promote and believe the solution to compression seal lubrication is the use of 2-stroke, outboard engine oil. A great deal of the aircraft rotary folks use 2-stroke oil in their fuel tanks. It's not unheard of to have engines lasting a substantially longer amount of time vs. 4-stroke oil metering. Combustion chamber surfaces remain much cleaner (much less carbon buildup). They also seem to run much better and smoother.

Kandy at Pettit pulled out a housing from an engine using the OMP and it had a nice shiney line around the middle of the housing where the engine oil was being injected. She then pulled a housing that was using premix. Nice and shiney all the way across.



I was a sceptic of pre-mix until she showed me that.



Not I am a firm believer in it. I just bought 3 gallons of Pettits Protek to mix. Up until this point I was using Amsiol.



We just put a hose nipple on the end of my injectors and clamped them off.

is it possible that a smoking engine could be caused by stuck linkage or a leaking omp on a 12a

I'm gonna say possible, but not likely. Don't have much experience with smokey motors, unless your burning out atf, then I have plenty of expereince

i have plenty of trans experience aswell

i havent seen the engne run yet im just going off what po said

and now that i think about it i will check the modulator line to see if the is a little oil in it

the trans has 160,000 miles on it and is a possible cause

thanks for getting my wheels turning

automatic flywheel bolts work very well. Your way will also work well.

they are supposed to be 1 way, but usually they arent



mike

what premix ratio are you guys using

i guessing a pint at every fill up
